[BIP-221] Set Protocol Fee Percentage to 50% on Gnosis Chain

PR with multisig payload:

https://github.com/BalancerMaxis/multisig-ops/pull/119

Motivation

Balancer has recently deployed to Gnosis Chain and is actively streaming rewards to several pools on the network. As deploying to a new network comes with no permissions automatically granted to the DAO or any other entities within the ecosystem it is important we activate all pieces of the system upon granting permissions. Tritium proposed to do so here, and governance passed the vote. In order for the DAO to be compensated with the protocol fee on the pools deployed on the network, governance must approve the activation of the 50% protocol fee on any new networks.

Specification

The DAO Multisig 0x2a5AEcE0bb9EfFD7608213AE1745873385515c18 will interact with the ProtocolFeePercentagesProvider at 0x41B953164995c11C81DA73D212ED8Af25741b7Ac and call setSwapFeePercentage using 0x4d44f0e9 twice. Once for the swap protocol fee, and once for the yield protocol fee.

Swap Protocol Fee:

The feeType(uint256) argument will be set to 0. The newValue(uint256) argument will be set to 500000000000000000

Yield Protocol Fee:

The feeType(uint256) argument will be set to 2. The newValue(uint256) argument will be set to 500000000000000000
